Abstract Three alcohol dehydrogenase genotypes, homozygous for either the electrophoretically fast, slow, or null allele at theAdh locus inD. melanogaster, were tested for relative larval alcohol preference behavior (APB) over a range of ethanol concentrations. Differences in behavior between genotypes were not significant at concentrations below 10%. At concentrations greater than 10%, avoidance behavior was negatively correlated with the relative ADH activity levels of the genotypes tested. A model based on the differential buildup of toxic acetaldehyde is proposed to explain the avoidance response.
